@lidio neto , I am sorry you are having battery level problems. I would agree with @themib , If you re-flash the stock OS and then do the same battery evaluation you may find that the problem was not the battery or calibration, but that it was the Cyanogen 12.1 OS. You may wish to try clearing cache before and see if that helps. Otherwise I can't make any suggestions as far as CM OS is concerned. Whenever you use a custom ROM, you may find peculiar functionality for one or another, or even many functions. The battery and metering system is no exception to this.

The battery doesn't actually "lose" large amounts of stored power over such dramatically short periods of time, so this must be a metering error. It may be that the calibration functionality isn't really working well, or that the metering system is somehow being misread by the OS. Either way, isolating the problem in a custom ROM is extremely difficult and you may be best served posting this question in a thread where others who are using CM OS can speak from similar experiences.
